Problems solved by technology

Vaseline oil is made from petroleum lubricating oil distillates of different viscosities, and the wax paste substance obtained by deoiling is also mixed with additives such as mechanical oil. Due to its relatively extensive preparation, asphaltenes and colloids in the petroleum jelly product oil There are many complexes of PAHs and polycyclic aromatic hydrocarbons, the fraction is too wide, the viscosity fluctuation range is large, the viscosity of the oil product changes too much with the temperature, that is, the viscosity-temperature performance is poor, so that the flash point, carbon deposition tendency, oxidation of the conductive paste product Stability and other physical and chemical properties are poor, and cannot meet the needs of connection point protection in current power transmission for energy saving, safety, long-term stability, and easy use

Embodiment Construction

[0040] Conductive composite grease process and product examples:

[0041] In a 5-liter vacuum kneader, add 600 grams of conductive graphite powder (1500 mesh), 100 grams of conductive carbon fiber (3mm), 300 grams of conductive nickel powder (1000 mesh), 2500 grams of low molecular weight polyisobutylene (molecular weight 2400), polyα - Olefin oil (viscosity 400mPa.s) 150 grams, isopropyl tri (stearyl) titanate 15 grams, fumed silica (specific surface area 200m 2 / g) 60 grams, industrial antifungal agent OBPA 10 grams. While heating up (maximum temperature does not exceed 120 degrees), while kneading, vacuumize after one hour, stop heating after 20 minutes, when the temperature drops to 90 degrees, add 15 grams of benzotriazole, and knead for five minutes Ready to pack.

Abstract

The efficient energy saving conductive composite grease consists of conducting agent 15-70 wt%, organic dispersant 23-80 wt%, thickener 1-6 wt%, and coupler 0.2-1.0 wt%. The conducting agent is one orseveral selected from graphite powder, conducting fiber and conducting metal powder;and the organic dispersant includes polybutylene and synthetic hydrocarbon oil. The efficient energy saving conductive composite grease may be used widely for the protection of various kinds of junctions in electric power transmission system, and has the advantages of saving in energy, safety, long term stability, simple usage, etc.

Description

technical field [0001] The present invention relates to a chemical product used in the electric power industry and electronic equipment, more specifically, the present invention relates to a chemical product used in the electric power industry and electronic equipment for electrical connection of conductors. Background technique [0002] In my country's existing power system, except for the power transmission and transformation system with a voltage level above 35kV, which is mainly responsible for long-distance transmission of electric energy, the voltage level of 10kV and 380 / 220V is the main body of the power distribution system and has the closest relationship with users. In the power part that is most closely related to users, including some DC power supply lines, electric energy is transmitted through various devices such as conductors, switches, and transformers. During the transmission process, power loss (active power and reactive power) will occur. , and produce en...
